Mesh has no "3D Representation" - SOLVED

[Anonymous]

I have this sporadic problem with a mesh element that represents my terrain.

It is a SOE "Subtract Upwards Target" of 9 other objects that consist of slabs, ramps and roofs. 8 of these are in a hidden SOE layer.

When I try to view the mesh in 3D (most of the time) it does not show, even when it is the only object selected.

However, when I delete the SOE operation of a visible slab (not hidden like the other 8 SOE operators), then it shows up in 3D.

On reapplying the SOE operation again it loses the ability to be seen in 3D

Today, while converting into a morph (just for the heck of it) I found that when all 9 operators are applied then I get the error meesage that says that "Only elements with 3D representation can be converted into morphs. No morph created". When I remove the SOE operation of the slab, then it successfully converts into morphs and also shows up in 3D in its native mesh form.

I do need the SOE operation of this slab. Is there anything I can do to fix this?

Thanks in advance.

Did you try to delete the problematic slab and create it from scratch? Maybe is a corrupted element.

Or maybe the Mesh has good geometry when no SEO is performed and will have corrupted geometry with the SEO performed.
You could try a test: move all the SEO operator elements a little bit in some direction, probably a bit in both X and Y direction from where they are, and do see if the result of the SEO now is displayed in 3D. If yes, then there is something with the SEO result.

Rocorona: yes did try that and did not work.

Laszlonagy: did that some time ago and the only thing that made a difference was when I moved the offending slab.

So I finally traced this to two things; both related to the geometry of the slab.

One was a octagonal hole that was setout to allow the elevator object to pass thru and the other was a very small V shape indentation on the outer boundary of the slab. Believe me when I say that I went thru all the outlines of the slab at a very high zoom along all edges.

Once I closed the octagonal hole and recreated it using another SOE operation rather than actual hole, and fixed the V shape indentation, everything is back to normal behavior.

Thanks for your input and time.
